Title
(EN) SURGICAL FLUID AND BLOOD LOSS MONITOR
(FR) CONTROLE DE LA PERTE DE SANG ET DE FLUIDE LORS D'UNE INTERVENTION CHIRURGICALE
Abstract
(EN)
This invention is a monitor to provide substantially real time estimates of fluid absorption rate and blood loss rate in a patient during a surgical procedure. The monitor estimates fluid source flow rates and waste fluid flow rates based on weight changes per unit time, or direct reading fluid flow rate meters. Blood loss flow rates are estimated based on hemoglobin concentration in waste irrigation fluid, and are used to correct waste fluid flow rates. Correct waste fluid flow rates are used in turn to obtain estimated fluid absorption rates. Optional verticality compensation means (93) (93') (93'), and anti-rotation devices (91) are included.
(FR)
Dispositif de contrôle donnant des estimations sensiblement en temps réel du taux d'absorption de fluide et de la vitesse de perte sanguine chez un patient au cours d'une intervention chirurgicale. Le dispositif de contrôle évalue les débits de fluide d'apport et les débits de fluides de rejet en fonction des changements de poids par unité de temps, ou par lecture directe de débitmètres mesurant le débit des fluides. Les taux de perte sanguine sont des estimations basées sur la concentration en hémoglobine du fluide d'irrigation rejeté, et permettent de corriger les débits de fluides de rejet. Les débits de fluides de rejet corrigés servent à leur tour à calculer des taux d'absorption de fluides estimatifs. Un dispositif optionnel de compensation de verticalité (93)(93')(93') et des dispositifs anti-rotation sont également décrits.
